Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds the technical provenance (Search-ShowAjax fragment) and the facet-derived nature of filters, which is useful context, but says nothing about pagination, rate limits, or result shape beyond what the output schema implies.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single dense sentence front-loads the core purpose and then threads the parameter hints. Efficient with no filler, though the semicolon chain is slightly compressed for reading.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be explained. The description covers purpose, input sourcing, and parameter formats adequately for a category-browse tool, leaving only minor behavioral gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema already documents path, sort, filters, page, and limit. The description largely restates the sort values and filters format already in the schema, adding only the 'live facets' origin detail, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Browse one Balenciaga category') and grounds it in the site's Search-ShowAjax product-list fragment. It distinguishes itself from balenciaga_categories by noting path is sourced there, but does not explicitly differentiate from siblings like balenciaga_product or balenciaga_search.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives prerequisites: path comes from balenciaga_categories, and filters are drawn from the response's live facets. This tells the agent how to obtain valid inputs, though it stops short of stating when to prefer this over the other balenciaga browse tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
